I had a squat/lunge/deadlift session a few days ago and oh boy did I feel my lower body this morning. I actually had trouble getting into and out of my car and spent all day at work limping around taking baby steps. My glutes are still tender

Ohh, I know that feeling. You did squats and lunges . No wonder you are sore. But I know you have been at this for quite sometime, so I am sure you know what you are doing. I'm still not a big fan of lunges - I think it is the balance part of it. I know they are great for all kinds of stuff including the core, but I usually quietly groan to myself when I see them on the workout list.
